ESAM 6600 - Looking for circuit schematics

Hi my display board backlighting has gone out and before I go and replace the whole board I wanted to make sure that it wasn't a simple diode or regulator that is blown.

Does anyone know where I can find the schematics for the machine?

Thanks

Just dug my ESAM6600 - PrimaDonna out of storage, its been there for a few years.
Although it all lit up, and made all the right noises, no water came out of the machine when you pressed any of the buttons.

I followed all the advice on here, checking for blockages, cleaning all the parts etc.
There was nothing obviously wrong, but sure enough replacing the 48W Water Pump, with a new £16 one from Amazon worked an absolute treat.

Thought I'd just say thanks to you all for posting the advice. As its got my machine up and running in less than a day.

Cheers Guys !
